1. First, remove the tapping screw with a screwdriver.

2. If the broken faucet can't find the screw, pry off the trademark sticker on the faucet-the front is where the screw is.

3. Prepare a drink bottle cap-drill a hole in the drink bottle cap with a knife.

4. The hole size of the bottle cap should be appropriate and centered-then tighten the screw.

Lock this water bottle cap at the beginning of the faucet-lock it.

6. This water bottle cap is the switch-try to see if the switch is normal. You can easily turn on and off the tap water without cutting your hands.
